Troubleshooting
ccasionally, you may encounter problems with your LMI
instrument or detector that may be repaired or resolved in the
field, saving turn-around time and expense in returning the
instrument to us for repair. Toward that end, LMI electronics
technicians offer the following tips for troubleshooting the most common
problems. Where several steps are given, perform them in order until the
problem is corrected. Keep in mind that with this instrument, the most
common problems encountered are detector cables and sticky meters.
Note that the first troubleshooting tip is for determining whether the
problem is with the electronics or with the detector. A Ludlum Model 500
Pulser is invaluable at this point because of its ability to simultaneously check
high voltage, input sensitivity or threshold, and the electronics for proper
counting.
We hope these tips will prove to be helpful. As always, please call if you
encounter difficulty in resolving a problem or if you have any questions.
